The color-coated galvanized sheet has been widely used in daily life. In different regions and different places of use, the PPGI with the same amount of galvanization will have a very different service life. What is the reason? What caused it?
In industrial areas or coastal areas, due to the effect of sulfur dioxide gas or salt in the air, the corrosion speed is accelerated, and the service life is affected. In the rainy season, the coating is wet by rain for a long time, or in places where the temperature difference between day and night is too large, and it is easy to be corroded, the service life will be reduced. Buildings or workshops made of color-coated galvanized sheets often have a long service life when they are often washed by rain, otherwise, they will be affected by the effects of sulfur dioxide gas, salt, and dust.
Therefore, when designing the roof, the greater the slope of the roof, the less likely it is to accumulate dirt and other dirt, and the longer the service life; those areas or parts that are not frequently washed by rain should be washed regularly with water. During storage, in a clean environment, to avoid corrosive intervention, the floor of the storage site should be flat and have sufficient bearing capacity. Except for some different types of color-coated galvanized sheets, which are not suitable to be directly placed on the ground, they should be placed on rubber pads or bracket devices. The storage place must be dry and ventilated. When you place it again, choose a location to minimize movement.
In order to make the color-coated galvanized sheet beautiful and tidy in use, and prolong its service life, the performance will not be affected during use. We should pay attention to the storage details mentioned in the article and protect it.
